Average files: ???AVG.nnn and OZOAVGYY.nnn
The Brewer is a ‘statistical’ instrument, and instantaneous deviations from the norm are not
uncommon. The purpose of average files is to provide a daily value for a specific measurement or
test result. It is normal to plot the data in average files vs time (days) to observe trends in data and
test results.
